Title: Customizable seat cushion and positioning assembly including pressure compensation inserts
Inventor: CHEW NORMAN
IPC: A61G7/057
Filed: 1999-11-03
Abstract: The invention relates generally to a seating system and more particularly to seat cushion assemblies having a rearward depression and cushioning insert tailored to fit under the skeletal structure of the user. In particular, the assembly preferably includes an intermediate insert which fits within a base depression and a cushioning insert which can be a fluid bag, air bag, foam or gel. The insert is generally oval shaped and has a rounded bottom.      This enables the cushion to be used to fit under the seating bones so as to provide a proper pelvic tilt.      Further, the insert can be moved in order to provide controlled movement of the pelvis over time.      A first cushioning insert is generally constructed of a material forming baffles so as to define air chambers and having a right and left seat bone area. A second design has a top and bottom so as to define the fluid envelope separated by central baffle having apertures to allow fluid communication between the right and left portions. In a further aspect, the invention includes tapered wedges which can be removed to lower one side of the leg well and the base cushion to allow for self-proportion on the part of the user. Rigid stabilizers support the edges of the base cushion.

Abstract: A shift shock in a stepped shift mode in a continuously variable transmission is to be diminished. A continuously variable transmission having an automatic shift mode and a stepped shift mode possesses a shift shock diminishing control function. In this control, when shift-down is made in the stepped shift mode (S.1), a timer is allowed to start counting (S.2) and the magnitude of deceleration G during change of the change gear ratio by a control motor is compared with a threshold value (S.4), and if the deceleration magnitude is larger than the threshold value, the supply of electric power to the control motor is stopped for only a very short time to decrease the deceleration G, thereby diminishing the shift shock (S.5).

Abstract: La présente invention, qui se rapporte la débitmétrie, concerne plus particulièrement les débitmètres à obstruction utilisés en série dans un conduit à fluides pour déterminer le débit volumique des phases liquide et gazeuse de fluides s'écoulant dans le conduit. Différents débitmètres parmi lesquels il y a au moins un débitmètre à obstruction sont disposés en série à l'intérieur d'un conduit d'écoulement tel qu'un tuyau. Des équations mathématiques sont développées pour chaque débitmètre en fonction de quantités mesurées et de débits d'écoulement par phase à l'intérieur du courant de liquide. On résout ensuite ces équations simultanément de façon à obtenir les différents débits par phase. On utilise deux débitmètres pour déterminer le débit de gaz ainsi que le débit de liquide. Selon une autre réalisation, on utilise trois débitmètres pour déterminer les débits d'écoulement d'un gaz et de deux phases liquides.
